The use of tissue water as a concentration standard in proton magnetic resonance spectroscopy ((1)H-MRS) of the brain requires that the water proton signal be adjusted for relaxation and partial volume effects. While single voxel (1)H-MRS studies have often included measurements of water proton T(1), T(2), and density based on additional (1)H-MRS(More)
The physics goals of the next Large Hadron Collider run include high precision tests of the Standard Model and searches for new physics. These goals require detailed comparison of data with computational models simulating the expected data behavior. To highlight the role which modeling and simulation plays in future scientific discovery, we report on use(More)
The search for events containing isolated leptons (electrons or muons) and missing transverse momentum produced in e ± p collisions is performed individually and in a common phase space with the H1 and ZEUS detectors at HERA in the period 1994–2007. The presented H1+ZEUS data sample corresponds to an integrated luminosity of 0.97 fb −1 , and comprises the(More)
Recent results of searches for leptoquarks, lepton flavour violating leptoquarks and excited fermions (electrons, neu-trinos and quarks) with the H1 experiment at HERA are presented, which use up to the full e ± p H1 data set. No evidence for the direct or indirect production of such particles is found. The results are interpreted in terms of limits on the(More)
The latest results from the H1 and ZEUS collaborations are presented on rare Standard Model processes and searches for physics Beyond the Standard Model. Intriguing events containing high transverse momentum leptons are observed by H1 and many competitive limits are set by both collaborations on the production of new particles in a variety of supersymmetry(More)
The study group on data preservation in high energy physics, DPHEP, is moving to a new collaboration structure, which will focus on the implementation of preservation projects, such as those described in the group's large scale report published in 2012. One such project is the development of a validation framework, which checks the compatibility of evolving(More)
The H1 data preservation project was started in 2009 as part of the global data preservation initiative in high-energy physics, DPHEP. In order to retain the full potential for future improvements, the H1 Collaboration aims for level 4 of the DPHEP recommendations, which requires the full simulation and reconstruction chain as well as the data to be(More)
Data from high-energy physics experiments are collected with significant financial and human effort and are mostly unique. However, until recently no coherent strategy existed for data preservation and re-use, and many important and complex data sets have simply been lost. While the current focus is on the LHC at CERN, in the current period several(More)
